Claims. (01.150 45) This invention relates to improvements in closuresfor bags, pocketbooks and'othr containers, and has for its principalobject the provision of aclosu re for bags or the likewhich wm'have manyof the merits and advantages of the socalled zipper closures, but whichwill be simpler in const'iuction and inexpensive to manufacture.

Another object of this invention is to provide aneffi cient bag closurewhich can be made lalf ?fposition shown in Fig. 5, the bars lzand l3 canbe pivotally rriov'd in relation to' each othr so as m pe'r'r'nit accessto the cements of;-the' bag. By nioving'the slider toward the openend-of the big, thejb ars iana I3fare brought-into closer 1y ofhon-metallic material which will be easy o p ate a d w i li w en t w t dcu l T Further objects of the invention will be ap parent from thespecif cation and drawing, in

Fig, 1 is a front elevational view of a bag; 2 is a perspective view ofthe -bag, with the slidepushed back, the bag ready to be; opened; Fig. 3is a section on the line 3 -3 of, 2; Fig. 4 is a fragmental detail ofthe endsof, the frame;

Fig. 5 is a section on the line 5-5 of Fig. 4 and Fig. 6 is aperspective detail of the slide piece. The numeral 10 indicates a bag towhich the closure is fastened by means of sewing or staples indicated asl8. The numerals l2 and I3 are the longitudinal frames or bars whichconstitute the principal body of the closure. At the meeting edges ofthe bars l2 and I3, the bar l2 has a locking projection or flange l4fitting into a. complementary groove IS in the frame l3. It is anadvantage if the angle of the projection I4 is somewhat broader than theangle of the groove or concavity l 5 so that when the bars are pressedtoward each other, the pressure of the bar [2 having the projection Mwill tend to look into the depression or groove l5 of the bar l3.

On the top of the bars or frames l2 and I3 respectively are grooves l6and I! in which the slider 2! operates. The grooves l6 and I! havewidened portions at their bases l6a and Ha respectively in which thestuds 25 and 26 having the projections 25a and 26a of the slider 2| fit,the numeral 22 indicating the angular body of the slider 2| and thenumeral 23 the finger piece of said slider.

The numeral 24 represents the open side of the bag to permit the bag tobe opened and the ends of the bars l2 and I3 to be widely separated fromeach other. The numerals l9 and 20 indicate the terminals of the groovesl6 and I1 and it will be seen that when theslider is in the "Thelongitudinal framesfor'bars 12am I3 ca n pretrably be'made of asynthetic plastic or other flexible material, as a certain elasticity'wouldfbe an advantage for certain uses'of this type of closurel f ebars or frames I2 and 13 can be madjeoi meta-l; howeverfiffdesired. It"is apparent that changes maybe maderin slider Z'IIi s ai-Q" thepositiohishowniindottedlines 't hout departing from the spirit'of myinvention.

It should also be noted that the tips of the slider and the grooves inwhich'th'e slider moves are so iashionedjthat the "slider cannot'b'elifted from the closure but is 'permanently'attached thereto in slidablerelation:
